HAY-TEDDER.

Specification of Letters Patent.

Patented Mar. 11, 1913.

Application ined ,nay 2, 1912. serial No. 707,266.

l'o all whom 'it may concern Be it-kndwn that 1, Jolis' R. Hlxuufns, a citizen of. the United States, residing at Macomjb,"i1i tliecounty of McDonough and State of'lllinois, have invented new and usefulImprovements in Hay-Tedders, of

-which the following is a specitication.

This inyention relates to hay tedders, 'and it 'has for'its object to produce a tedder of simple and efficient -construction which -may be conveniently attached to and operated in con-junction with a mowing machine of any -throw the tedding device into and out of gea-r, and'also to raise it from or lower it -toward the ground, as may be required.

With' these and other ends in view whichwill readily appear as the nature of the invention is better. understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafterl fully described and particularly pointed out in the claim.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however', understood that no limitation is necessarily made to the preciSe;structural details therein exhibited,

butthatchangeS, alterations and moditica' tions within the scope of the claim'may be resorted to when desired.

In the drawings,-Figurc 1 is a top plan `'view showing the tedding deviceapplied to a mowing machine of ordinary conventional type in position for operation. Fig. 2 is a top plan view of the tedding device detached. Fig. 3 is; a side elevation 'of the device` as seen in Fig. 1. Fig. 4 is a rear elevation. Corresponding parts in the several figures are denoted by like characters of reference. The main frame of theimproved tedding I deviceA is preferably made of angle or channeled iron or steel, the same being bent t0 approximate U-shape to present side mema rear member or bridge piece 3. The side members 1 and 2 are provided -with bracket lmcn'ibers 4, whereby they maybe pivotally connected with the frame of a'mowing machine A of ordinary construction. The mowing machine has been Shown as being. equipped with ground engaging driving wheels B with which the pivotal brackets 4 are'preferably in axial alinement.

Suitably, clamped upon or otherwise connected with one'of the wheels B is a .sprocket` wheel 5, the Same lying between the mower wheel'and the side member 2 of the tedder frame. The side members 1, 2 of the teddcr frame are provided with bearings (i for a. shaft 7 having a plurality of cranks 8 and equipped with a sprocket pinion 9 which is connected with the"sprockct wheel 5 by a chain or link belt 10: The sprocket wheel t), which is loose on the shaft 7, islirm'idcd with a sleeve llcarrying a clutch member 12 adapted to be engaged by-a mating clutch member 13 whichis slidable upon and rcvoluble with the shaft- 7, said clutch member 13?) being actuated by a shipping lever 14 whereby it may be placed into or out of en. gagement with the'clutch member 12, which latter maybe operatively connected with the shaft 7 by means of the clutch members 12, 13 when said clutch members are in engagementwith Veach other Vihcn` this is the case, motion will be transmitted from the sprocket wheel 5 to Vthe shaft 7 when the mowing machine is in operation, and said motion may be interrupted by disengaging the clutch members 12, 153.

'bers 1 and 2 that are connect-ed together by Suitably mounted on the tongue C of the mower, where it. may be secured by means of clamps, bolts or in any other'convcnient manner, is a bracket 15 havinga bearing sleeve 1G wherein a shaft- 17 is Supported for oscillation, said shaft being provided with cranks 18 and with a lover 19 whereby itmay be rocked. The lever l5) has a spring actuated catch 2() adapted to engage a segment rack 21 formed on the bracket 15 and whereby the crank shaft. 1-7 and related parts may be held securely at various ad? justments. The cranks 18 and thc shaft 17 are comm'cted by link rods with lugs or brackets 23 on thc bridge piece 3 of the tedder frame, lwhich latter, by means of thc lever 19 may be .swung about itsaxis so as to raise or lower the rear end thereof. The

link rods 22 also'serve to support a cross bnr 2i carryingears or lugs A similar ear or lug 25 1s secured on the side bar 1 of the tedder frame.

Tedder forks 2G of ordinary construction are provided with handles 27 .which are pivoted on the cranks S of the shaft 7. said han dles being also connected by link rods with the ears or lugs 25 and 25' that are located in approximate alinementwith the respective cranks. y

The side member 2 is extended forwardly of the supporting bracket 4, and said side member carries a shield or casing 30 which serves to inclose the lower portion of the sprocket wheel 5 and the lower lead of the chain 0r link-belt 104to revent the said chain and sprocketfrom being clogged with grass. Y

It will be seen from the foregoing descrip` tion, taken in connection with the drawings hereto annexed, that when the improved attachment is applied to a mowing machineY and .the latter 1s in operation, the tedder frame will extend rearwardly of the molwer,

frame, and the crank shaft 7 will be driven by the chain or link belt l0. The tedder forks will thus be carried around by the cranks 8, oe-ing thereby reciprocated vertically, vsaid forks receiving at the same time a rocking motion by means of the link rods Q8, whereby the hay engaged by said forks will be tossed and thrown loosely in a rearward direction. At each round of the mowing machine, the swath cut by the preceding round will be engaged by the tedder attachment, and the grass will thus be tossed and loosened while still green and before` it. has a chance to dry and become crisp; the curing of thehay will, therefore, progress" more speedily and satisfactorily than where the tedding is performed at a much later time The combination with a mowing machine,

ofla tedder attachment comprising a U- shaped frame including a rear cross bar and forwardly extending side members, the latter pivot-ally associated with the `mower frame, a bracket secured on the tongue of the mowing machine and having a bearing sleeve, a rock shaft supported in said sleeve and having terminal cranks, link rods connecting said cranks with 'the rear cross bar of the U-shaped frame, means for oscillating the rock shaft and for securing it at various adjustments, a crank shaft journaled on the U-shaped frame, means including a clutch for transmitting motion to the crank shaft from the mowing machine, tedder forks having handles fulcrumed. on the cranks of the shaft, a cross bar supported on thelink rods,-

lugs on said cross bar and on one Side bar of the U-shaped frame, and rods connecting said lugs with the handles of the tedder orks. y

In testimony whereof I aix my signature in presence of two witnesses.
